Bochy was added as part of the team's September call-ups, with rosters now expanded to 40 players.
Selected by the Giants in the 20th round of the 2010 MLB draft out of the University of Kansas, Bochy, 27, has never appeared in the major leagues. He has a 3.83 ERA in 35 appearances, including two starts, at Fresno this season. Over four minor league seasons, Bochy's ERA is 3.03.
The Giants entered Tuesday at 75-63, two games behind the Los Angeles Dodgers in the National League West and currently in possession of the first NL Wild Card spot.
